Based on the injection-production well test and reservoir distribution characteristics, the paper works out an adjusting injection-production plan for V oil group in XX oil field by analysing the injection structure.

Nonlinear percolation feature in low permeability reservoir;

Flow unit classification and microscopic percolation feature of Toutunhe Formation reservoir in Santanghu Oilfield

The field dynamic development data present that the low-oil saturation oil reservoirs have obviously different percolation features with common oil reservoirs.

The flow unit is defined as the same reservoir unit with identical seepage features, and it is considered that the flow unit is relative and in some level and scale.

Study on physical modeling and percolation characteristics in dual-media reservoirs;

The experiments show that the intrinsic factors such as colloid, bitumen and wax content determine its rheological properties, while the external factors such as temperature and permeability of porous medium as well as the existing of non-flowing phases will have some influence on the percolation characteristics of crude oil.

The granite buried hill reservoir in block Leng124 shows the percolation characteristics of dual porosity media.
